Architecture diagram


To get most out of this course, you should feel comfortable with coding and command line,
and know the basics of SQL. Prior experience with Python will be helpful, but you can pick
Python relatively fast if you have experience with other programming languages.

Prior experience with data engineering is not required.



  • Q: I registered, but haven’t received a confirmation email. Is it normal?
    A: Yes, it’s normal. It’s not automated. But you will receive an email eventually
  • Q: At what time of the day will it happen?
    A: Office hours will happen on Mondays at 17:00 CET. But everything will be recorded, so you can watch it whenever it’s convenient for you
  • Q: Will there be a certificate?
    A: Yes, if you complete the project
  • Q: I’m 100% not sure I’ll be able to attend. Can I still sign up?
    A: Yes, please do! You’ll receive all the updates and then you can watch the course at your own pace.
  • Q: Do you plan to run a ML engineering course as well? A: Glad you asked. We do ?
